CAR-PART.

Chicago,'in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in 'CarParts, of which the following is a specification.

My invention relates to railway car construction and particularly to an improvement applicable to refrigerator cars.

In-the construction of refrigerator cars it is common 'to' build the same with a wooden underframe consisting of center, intermediate and side sills, the center sills being re inforced and strengthened by applying thereto adraft ai'iii extending continuously from the buffer block or' end sill to a point. a substantial distance to the rear of the bolster one of these arms being applied to each of the center sills. In the, construction of such arms a portion is provided which un derlies a center sill and a portion which lies alongside of the sill. It is also essential in the construction of such ears that a double floor be provided; that is, in addition to the ordinary floor asub-floor or Wall located between the sills. The manner of supporting this sub-floor at the point occupied by the draft arm has occasioned considerable difficulty and the present invention relates to the provision of means for readily and securely supporting the floor.

"he i'esultis secured by providing on the draft arms a laterally projecting shelf or ledge which extends from end to end of the metallic member.

The invention will be more readily understood by reference to the accompanying drawings, wherein;

Figure l is a side elevation of a draft arm constructed in accordance with my inven- Fig.2 is a tion transversesectional view on the line 2-2 of F ig. 1, and

Fig. 3 is a similar view on the line 33 ofFig- In the drawings the center sills are indicatedat 10, and an intermediate sill at 11. A-floor 12, of the usual construction is superposed thereon. As a means for support ing the draft rigging and strengthening the Wooden center sills, the draft arms, each formed as a massive casting, are applied thereto. These arms each include a draft rigging supporting portion 13, a portion 14, which extends over the bolster, and the porspecification of Letters Patent.

tion 15, which is secured to and underlies the sill at the rear of the bolster. It will be noted that the casting has a vertical web which lies alongside of the center sill and extends from the end sill 16, to a point a substantial distance to the rear of the bolster. ()n this vertical web I cast an integral, laterally projecting ledge 17, adapted, as best shown in Figs. 2 and3, to support a sub-floor 18, the opposite end of the floor boards being supported on a projection 19, carried by the intermediate sill 11. The lodge will. be so positioned as to overlie with suliicicnt clearance the truss rod saddle 20, and underlie the strengthening flange 21, which projects from the portion 14-.

By the use of this construction all fitting of boards around the reinforcing casting is avoided. if it be desired to securely fasten the boards to the casting, bolts may be passed through the boards and the ledge in the usual manner.

I. claim: 1. In a railway car, the combination With ad acent longitudinal sills of a metal re1nforcing member for one of saidsills, said member being provided with a laterally proecting ledge, and an insulating floor sup ported at one side on said ledge and at an other side on the side of an adjacent sill,

substantially as described.

2. In a railway car, the combination of longitudinal wooden sills, a metal reinforc- '90 car, said member. being provided With an integral, laterally projecting ledge, the lower floor boards being supported on said ledge and the side of the diate sill, substantially as described.

4. A draftarm in the form of a casting adapted to lie alongside of a Wooden sill and to eXtenda substantial distance rears Wardly from the end of the car, said casting being provided With an integral, lateral on said ledge, substantially as de-- adjacent intermeiudgg'e exi'vnding substantially 1-0111 and t0 vnd oi Hm mshng and ululfed. to suppor and extending substs ih'ureo'i and an l-nsuia' on said mm t m 5111., sul'is'tantlauy cie Slgneii at Ch1102.550 Hi, April, 1918.
